The matter is certainly delved into. But some understanding of some biology material can help.
Orchids can often produce new orchids by growing new bulbs or new plants (with roots) attached to the orchid itself. Regardless of where it is connected --- eg. on the rhizome, or on a flower spike, or on an existing bulb ----- this is one way for an orchid to produce new plants -- via this 'vegetative' propagation pathway. The attached baby orchids eventually develop enough (ie. gets big enough, and having enough roots) to become independently grown if we cut the juvenile away from the main plant. These 'new' plants have the same DNA as the main plant. That is - same features. Genetically the same.
They can also be propagated (also vegetative propagation) in labs, where they take particular 'suitable' tissue from a particular individual orchid ..... and cut it all up into bits, and then those bits grow into new juvenile orchids. This is the cloning or 'meristem' propagation method ----- where most of the orchids produced from this approach ---- usually results in orchids having the same DNA as the original plant. But this process doesn't guarantee identical DNA for every produced new plant. So it can be a case of 'luck of the draw' for buyers that actually want a 'copy' of the original. They might not always get what they were looking for.
And then there are seeds. But any individual seed that develops into an orchid will not have the same DNA pattern as another seed from the same batch (or same seed pot) ----- because each seed is an individual - which is along the same lines as un-identical brothers and sisters from human parents (ie. not including 'identical twins'). This is assuming there there is no possibility of having 'identical twin' seeds that within a seed pod.
So - if you're looking for a 'particular' individual orchid ----- then it's unlikely that we can get that orchid by using a seed.
Although - it is known that the
SEED-grown off-spring of species orchids typically have very similar features (flowers etc) as the parents (if the two parents come from the same species). This is in 'general'.
